NASA Delays Sky Mapper Launch to Saturday

NASA has delayed the launch of its new infrared sky mapper by at least a day, with liftoff now scheduled for no earlier than Saturday. The Wide-field Infrared Survey Explorer (WISE) is now slated to launch on Dec. 12 between 9:09:33 and 9:23:51 a.m. EST (1409 and 1423 GMT) from California's Vandenberg Air Force Base. The flight was already threatened by cloudy weather predictions for Friday, and now NASA has decided to push back the launch to allow engineers to troubleshoot a glitch in a booster steering engine on the Delta II rocket slated to carry the observatory to orbit.
